What kind of oil should be added for power steering?

Add power steering fluid. The following is a related introduction about the power steering pump: Classification: Power steering systems can be roughly divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. The mechanical hydraulic power steering system is generally composed of components such as a hydraulic pump, oil pipes, pressure and flow control valve body, V-type transmission belt, and oil reservoir. Definition: The car power steering pump refers to a component that helps improve and stabilize car performance. It mainly assists the driver in adjusting the car's direction. Currently, most cars are equipped with power steering pumps, mainly including the steering power steering pump and the brake vacuum power steering pump.
I've been driving for decades and am quite particular about power steering fluid. Generally, you should add dedicated power steering fluid, or automatic transmission fluid (ATF) also works well, especially for older cars due to ATF's good compatibility. The key is to follow the vehicle manual's recommendations—never add the wrong fluid like engine oil or brake fluid, as that can wear out the power steering pump, leading to heavy steering, leaks, or even hose bursts. Regular fluid checks are crucial: inspect the level against the markings when the engine is cold before starting, ensuring it's within the middle range and not overfilled. If the fluid appears too dark or has a burnt smell, replace it. I recommend checking every two to three years to avoid failures while driving. Proper maintenance ensures smooth steering and extends the system's lifespan.
I just got my driver's license and often study these small details. For power steering fluid, it's best to use power steering fluid or ATF, don't substitute with household lubricating oil otherwise the steering may squeak or become stiff when turning. Check the manual to confirm your vehicle's requirements, some cars use special bottled fluid available at supermarkets. During self-inspection, with the engine cold and turned off, open the hood to locate the fluid reservoir, ensure the fluid is clear without bubbles and the level is at the standard mark. Forgetting to refill may overload the system and easily damage the pump, repairs can be expensive and not worth it. If you feel the steering wheel becoming heavier while driving, stop to check first, don't force it, safety is the top priority.
As an ordinary car owner, here's a simple explanation about power steering fluid maintenance. Usually, you just need to add dedicated power steering fluid or automatic transmission fluid – never use irrelevant liquids like engine oil. For the procedure: turn off the engine, open the hood, locate the transparent reservoir, check the fluid level against the markings (keep it around the middle range). Replace immediately if the fluid appears dirty to prevent steering noise and stiffness. Note that newer cars with electronic power steering may require no maintenance, but this advice specifically applies to hydraulic systems – always confirm your vehicle's specifications to avoid missing crucial maintenance.
